What Are The Major Functions Of Circulatory System – The respiratory and circulatory systems work together to maintain homeostasis. The circulatory system has three important functions. transport of blood, gases and nutrients collection of waste materials maintenance of body temperature oxygen-poor blood oxygen-rich blood
System; It includes the heart, arteries, veins and capillaries. heart pumps blood throughout the body arteries carry blood away from the heart vessels carry blood back to the heart capillaries carry blood to and from the cells veins arteries

What Are The Major Functions Of Circulatory System
Valves in each chamber prevent backflow of blood. aortic valve left atrium mitral valve left ventricle septum pulmonary valve right atrium tricuspid right ventricle Muscles compress the chambers with a powerful pumping action.
The Functions Of The Skeletal System
The lungs contain bronchi, bronchioles and alveoli. Millions of alveoli provide the lungs with a large surface area. Alveoli absorb oxygen from the air you breathe. alveolar bronchiole
Air flows from high pressure areas to low pressure areas. The air was breathed. The muscles contract and the rib cage expands. The diaphragm flattens and moves downward. The air was vented. Muscles and rib cage relax. The diaphragm relaxes and rises.
Oxygen and carbon dioxide are transported to and from the alveoli by the blood. oxygen diffuses from the alveoli to the capillaries oxygen binds to hemoglobin in red blood cells carbon dioxide diffuses from the capillaries to the alveoli ALVEOLIES GAS EXCHANGES alveoli capillary co2 o2 Co2 diffuses into the alveoli. O2 mixes with the blood. capillaries
Pulmonary & Systemic Circulation
2 Red Blood Cell Nerve Cells: Nerve cells, or neurons, look different from red blood cells and have different functions. They act like telephone wires, carrying and transmitting messages. Some of these cells can reach 2 meters in length!
3 RBC Function: Carries oxygen from the lungs to the body, removes carbon dioxide from the body and returns it to the lungs. Oxygen binds to hemoglobin.
4 White Blood Cell Nerve Cells: Nerve cells, or neurons, look different from red blood cells and have different functions. They act like telephone wires, carrying and transmitting messages. Some of these cells can reach 2 meters in length!
There are 3 main types of WBC. Those who describe the invaders. Others swallowing the invaders. And those that have more than one nucleus to create immunity.

6 Platelets Nerve Cells: Nerve cells, or neurons, look different from red blood cells and have different functions. They act like telephone wires, carrying and transmitting messages. Some of these cells can reach 2 meters in length!
7 Platelets Function: Red blood cell parts that help form blood clots. Produce fibrin, a material that forms a network to trap blood cells.
Any blood cells (assuming you’re not using them for the skeletal system). Temperature regulation Blood pressure Heart Rate `
12 Arteries: Function: carries blood away from the heart. Relationship between Structure and Function: The walls are strong and flexible, allowing them to withstand high blood pressure.
Digestive, Excretory, Respiratory, And Circulatory Systems
13 Function of Capillaries: It is the place where substances are exchanged between blood and body cells. Relationship of Structure to Function: Thin walls allow nutrients and waste to spread.
14 Vein Function: Carries blood to the heart. Relationship of Structure to Function: Thin walls allow skeletal muscles to push blood back to the heart.

3 How do your heart rate and breathing rate change when you switch from walking to running?
They are increasing. 2) In your experience, what factors might have intervened to make it difficult for you to breathe? Being out of shape High Altitude Asthma Extreme Hot/Cold weather Allergies Respiratory infection Secondhand smoke or being a smoker Pollution Chemical smog disease
The respiratory and circulatory systems work together to maintain homeostasis. The circulatory system carries blood and other substances to and from cells carries materials from cells to cells removes waste separates oxygen-poor and oxygen-rich blood Oxygen-poor blood Oxygen-rich blood
1) transportation of blood, gases, water and nutrients to cells 2) collection of waste materials (CO2) 3) maintenance of body temperature
Human Cardiovascular System Organs, Functions, Diseases
Arteries Pg in the book veins Circulatory System Red blood cells hemoglobin capillaries heart You need a description and pictures for each
The system includes: heart pumps blood throughout the body arteries carry blood away from the heart Oxygen-rich blood vessels transport blood back to the heart Oxygen-poor blood capillaries transport blood to and from tissues *Where gas, water, and nutrient exchange occurs Blood Vessels
9 red blood cells – receive oxygen from the lungs and deliver it to all body cells; takes in CO2
O2 binds to hemoglobin, giving blood its reddish color. Blood only becomes bright red when it absorbs oxygen.

Think: What does the respiratory system bring into your body? How does the circulatory system distribute this product? What waste product does blood remove from cells? How does our body get rid of these wastes?
How do the respiratory and circulatory systems interact? The lungs bring oxygen to the body, the circulatory system (blood flow) carries this oxygen to all cells of the body. The blood flow also takes waste (carbon dioxide) from the cells and expels this waste as carbon dioxide when we exhale (exhale).
Solution: Science The Blood Circulatory System Parts And Functions Study Notes
Blood consists of approximately 45% solids (cells) and 55% liquids (plasma). Plasma consists largely of water and contains proteins, nutrients, hormones, antibodies, and dissolved waste products.
(red cells) are small red disc-shaped cells. They contain HAEMOGLOBIN, which combines with oxygen in the lungs and is then transported to body cells. Hemoglobin then returns carbon dioxide waste to the lungs. Erythrocytes form in the bone marrow at the knobby ends of the bones.
(white cells) help the body fight bacteria and infection. When a tissue is damaged or infected, the number of leukocytes increases. Leukocytes form at the small ends of the bones. Leukocytes can be classified as granular or nongranular. There are three types of granular leukocytes (eosinophils, neutrophils, and basophils) and three types of nongranular (monocytes, T-cell lymphocytes, and B-cell lymphocytes). See also lymphatic system.
(platelets) help in the formation of clots in the blood by releasing various protein substances. When damage occurs in the body, platelets break down and enter into a chemical reaction with proteins found in the plasma, which ultimately forms a thread-like substance called FIBRIN. Fibrin then “captures” other blood cells forming the clot, preventing further blood loss and laying the foundation for healing.
Nervous System Overview
It removes oxygenated blood from the heart. They are thick hollow tubes that are highly ELASTIC, allowing them to EXPAND (expand) and contract (constrict) as blood is pushed downwards by the heart. Arteries branch and re-branch, shrinking until they become smaller ARTERIOLES that are even more elastic. Arterioles supply oxygenated blood to capillaries. AORTA is the largest artery in the body, which receives blood from the heart and branches into other arteries that send oxygenated blood to the rest of the body.
It distributes nutrients and oxygen to the body’s tissues and removes deoxygenated blood and waste. They are extremely thin, with walls only one cell thick, and they connect arterioles to venules (very small vessels).
(very small veins) join the VEINS that carry blood back to the heart. Vein walls are similar to arteries but thinner and less elastic. Veins carry deoxygenated blood towards the lungs, where oxygen is removed via pulmonary capillaries. PULMONARY Veins then carry this oxygenated blood back to the heart.
The heart is a hollow, muscular organ that beats more than 100,000 times a day to pump blood through the body’s 60,000 miles of blood vessels. The right side of the heart receives blood and sends it to the lungs for oxygenation, while the left side receives oxygenated blood from the lungs and sends it to the body tissues. The heart has three layers; ENDOCARDIUM (inner layer), EPICARDIUM (middle layer) and MYOCARDIUM (outer layer). The heart is protected by the PERICARDIUM, the protective membrane that surrounds it.
Blood Flow Through The Heart And Lungs
There are four chambers in the lower part of the heart
